High-lead Ballscrews are essential elements and parts for high-speed machine tools of next century.

Features

It is important for a High-lead Ballscrew to be with characteristics of high rigidity, low noise and thermal control. PMI 's designs and treatments are taken for following:

High DN Value

The DN value can be 130,000 in normal case. For some special cases, for example in a fixed ends case, the DN value can be as high as 140,000. Please contact our engineers for this special application.

High Speed
PMI 's High-speed Ballscrews provide 100 m/min and even higher traverse speed for machine tools for high performance cutting.
High Rigidity

Both the screw and ballnut are surface hardened to a specific hardness and case depth to maintain high rigidity and durability.
Multiple thread starts are available to make more steel balls loaded in the ballnut for higher rigidity and durability.
